The Dead And The Damned (2018)

When Captain Merric Stockwell returns from Afghanistan he's a broken man. One of only three survivors of a brutal engagement in the mountainous and forgotten Nangarhar province, he struggles to remember the tragic events of that fateful day, troubled by the inconsistencies in the official government account, and plagued by terrifying demonic visions of events he can't be sure of. Back in London, Stockwell's life is falling apart. Riven with guilt over the deaths of his men and tormented by the ongoing hallucinations, he suddenly finds himself at the centre of a murder investigation when the surviving members of his unit begin to die gruesomely. This brings Detective Inspector Alexandra Granger into the fray. In a twenty year career, the murders of Stockwell's men are the most brutal she's ever seen. For a London cop, that's saying something. Granger is confounded by the senseless, inhuman nature of the slayings. The only thing that ties them together is the military background of the victims; both soldiers, both survivors of the massacre at Nangarhar. As Stockwell wades deeper into the mystery of his comrades murders, and the events behind the massacre at Nangarhar, he learns that his terrifying visions are more than just hallucinations, and that the horrors of war are as nothing, compared to the malevolent evil that has followed him home. But the question will be raised; is Stockwell truly facing the threat of an ancient, supernatural evil, or is he a man teetering on the precipice of loosing his mind, a victim of his own tormented psyche.
